Activating/Deactivating the virtual surround sound
The RS 175 headphone system offers two virtual surround modes
(high
HI
/low
LO
)
 
that simulate the sound generated by external stereo
speakers, thus, producing spatial and livelier sound.
The intensity of the surround effect however differs according to the mode
selected. Depending on your personal preference for spatial sound quality,
you can set the mode to either high 
HI
 or low 
LO
.
Press the 
SURR 
button on the headphones or the transmitter.
The surround effect toggles between off and the 2 surround sound
modes, as indicated by the 
LO
HI
 LEDs.
